Triumph of the Siblings: The Battle Between Good and Evil

In a world of magic and power, three siblings stood out among the rest. Two sisters and a brother, all born with extraordinary abilities, were destined for greatness. The sisters, kind and compassionate, used their powers to help those in need. The brother, on the other hand, was consumed by his own ambition and desire for power.
As they grew older, the sisters became known throughout the land for their acts of heroism. They fought against evil and protected the innocent, using their powers to heal and protect.

The sisters tried to reason with their brother, but he would not listen. He believed that he was meant to rule, what will the 2 girls do to save the world?
